added "how to" (specify the path to executable) to the main doc node
ISPROJECTIVE works with Bertini Refine and Bertini Parameter Homotopy
USERHOMOTOPY has ISPROJECTIVE functionality
Two new functions and updated documentation for referee report.

importPoints reads a standard solution text file and makes it into
points that you can manipulate in M2

phPostProcess takes a directory as your input that is ready to a do a
stage two parameter homotopy and a list of parameters and outputs a
list of points.
Merge branch 'NAG' into Bertini

added a "solutionType" option to phPostProcess
added the option allowStrings

Bertini ZeroDimSolve, PosDimSolve, TrackHomotopy, Parameter Homotopy
now have the option of inputing the polynomials as strings.
tst files and documentation were also added.
added subFunction option

Allows you to write subfunctions into the bertini input file.
Renamed the options allowStrings and subFunctions to AllowSstrings and SubFunctions
Fixed a bug in phPostProcess and added a phMonodromy function.

phMonodromy is built on top of phPostProcess.
