ManeParse: A Mathematica Interface to the PDFs

ManeParse is a modular Mathematica package that provides access to PDFs for hadronic calculations. It allows for parsing of .pds and LHAPDF6 files and estimates PDF errors for Hessian and MC releases.

KNOWN ISSUES: ManeParse version 5.0, Mathematica package:

Known issues:
Note: When parsing the xxx.info file MMA reads a line at a time. Thus a \cr in a field (such as SetDesc:) will case confusion. This happens in RARE cases such as HERAPDF20_NLO_VAR. The solution is just to remove the \cr in SetDesc: in the xxx.info file
In certain instances, the alpha-S routines may break and return an infinite loop. This can be fixed by calling a pdfReset[] before loading the PDF sets.

NEW FEATURES: ManeParse Mathematica package:

New Features:
pdfFunctionX[]: (Vers.4.0+) This function returns the interpolated value of the x*PDF. As the LHAPDF grids store x*PDF, this does a straight interpolation of the grid, in constrast to the pdfFunction[] function which divides by x. This function is particularly useful for Structure Function tables which can be interpolated directly.
Parsing of xxx.info file: (Vers.5.0+) Starting in V5.0, the parsing of the info files was simplified. This will no longer get confused by unmatched single or double quotes in "SetDesc:" strings. HOWEVER, it will get confused if a field is split over multiple lines with \cr. The solution is to simply remove the \cr in the info file. This happens rarely.
