#### DOCUMENTATION ####
# users should be (a) creating faculty objects and (b) running checkCommittee.
# the other functions here are internal.
### the faculty function
# arguments:
# name: string, faculty name (only used in printing, so can be however you identify this faculty member)
# dept: string, name of department where faculty has his/her primary appointment
# rank: string, faculty rank. should be "assistant","associate","full", or "scientist"
# sph: boolean, whether or not faculty's primary appointment is in the School of Public Health. Default TRUE.
# advisor: boolean, whether or not this faculty is your primary advisor. Default FALSE.
# mydept: boolean, whether this faculty is primarily appointed in your department. Default TRUE,
# alt: boolean, whether you're considering this faculty member as an alternate. Currently only used in preliminary exam mode. Default FALSE.
# joint: string, name of department where faculty has his/her joint appointment. Only used in thesis committee mode. Currently only supports one joint appointment, but is only important if the joint appointment is in the student's primary department.
# return:
# a list with elements named the same as the arguments.
### the checkCommittee function
# arguments:
# ...: several faculty objects created with the faculty function.
# mydept: string, name of student's primary department
# type: string, which type of committee is being formed ("prelim" or "finaldefense")
# return:
# none, but either exits with error if committee is not valid, or prints the valid committee.
