#' Simplified loading and installing of packages
#'
#' This is a wrapper to \code{\link{require}} and \code{\link{install.packages}}.
#' Specifically, this will first try to load the package(s) and if not found
#' it will install then load the packages. Additionally, if the 
#' \code{update=TRUE} parameter is specified it will check the currently 
#' installed package version with what is available on CRAN (or mirror) and 
#' install the newer version.
#' 
#' @param pkgs a character vector with the names of the packages to load.

#' Set function parameters for debugging.
#' 
#' Sets the defauls for the parameters in the given function witin an environment.
#' 
#' @param fun the function whose parameters should be set.
#' @param envir the environment to set those parameters.
#' @param missing.value value to assign to parameters that do not have a defautl value.
#' @param overwrite should parameters already defined be overwritten.

#' Returns the year (fiscal or calendar) and quarter in which the date appears.
#' 
#' This function will cut the given date vector into quarters (i.e. three month
#' increments) and return an ordered factor with levels defined to be the quarters
#' between the minimum and maximum dates in the given vector. The levels, by
#' default, will be formated as \code{FY2013-Q1}, however the \code{FY} and \code{Q}
#' can be changed using the \code{fy.prefix} and \code{quarter.prefix} parameters,
#' respectively.
#' 
#' @param x vector of type \code{\link{Date}}.

#' Convert a list of vectors to a data frame.
#' 
#' This function will convert a list of vectors to a data frame. This function
#' will handle three different types of lists of vectors. First, if all the elements
#' in the list are named vectors, the resulting data frame will have have a number
#' of columns equal to the number of unique names across all vectors. In cases
#' where some vectors do not have names in other vectors, those values will be
#' filled with \code{NA}.
#' 
#' The second case is when all the vectors are of the same length. In this case,

#' Parse a codebook file with variable and level information.
#' 
#' Parses a codebook file where lines starting at column zero (far left) represet
#' variable information (e.g. name, description, type) and indented lines 
#' (i.e. lines beginning with white space, either tabs or spaces, etc.) represent factor
#' levels and labels. 
#' 
#' Note that white space at the beginning and end of each line is stripped before
#' processing that line.

require(xtable) 
 
#' Prints a LaTeX table with numeric columns aligned on their decimal points.
#' 
#' This function wraps the \code{\link{xtable}} and \code{\link{print.xtable}}
#' functions in the \code{xtable} package so that numeric columns are aligned
#' on their decimal place.
#' 
#' See \url{http://jason.bryer.org/posts/2013-01-04/xtable_with_aligned_decimals.html}
#' for more information.

#' Creates a dialog box using tcl/tk to get input from the user.
#' 
#' This function will create a tcl/tk dialog box to get user input. It has been
#' written to be extensible so the R programmer can easily create a dialog with
#' any number of varaibles with custom labels and data conversion of the user
#' entered data. The function will return a list where the element names are
#' \code{vars} and the value is the user input. By default, all entry will be
#' converted using the \code{as.character} function. However, this can easily be
#' altered using the \code{fun} parameter. For example, if integers are required,
#' use \code{fun=c(as.integer, ...)}. It is also possible to write custom
