shpec carryover examples

README.md

Illustrates carryover between shspec examples.

Carryover example to example:

$ shpec carryover_it_to_it.sh
shpec
  shares state between examples a
  shares state between examples b
  (Expected [] to equal [value])

real  0m0.002s
user	0m0.001s
sys	0m0.000s
2 examples, 1 failures

Carryover file to file, resulting in order dependence:

$ shpec carryover_file_to_file_{a,b}.sh shpec
  shares state between files a
shpec
  shares state between files b
  (Expected [] to equal [value])

real	0m0.003s
user	0m0.002s
sys	0m0.001s
2 examples, 1 failures

$ shpec carryover_file_to_file_{b,a}.sh
shpec
  shares state between files b
shpec
  shares state between files a

real	0m0.002s
user	0m0.001s
sys	0m0.000s
