Adds an unfinished top.f90 which reads and parses the top files
Continue writing top.f90 to parse the top files
Adds count_record_in_string() in utility.f90
top.f90 is finished

atom mass and charge in top files can be read if they are
written in the [ atom ] records under [ moleculetype ]

Reading [ atomtype ] is not implemented
Makes top.f90 read information from [ atomtypes ]

and adds several improvements to accomodate the needs of
oneTwoDecompose.f90
Incorporates top module to oneTwoDecompose.f90

oneTwoDecompose.f90 now reads top files and calculates the
correlations of center of mass between molecules.
Merge branch 'oneTwo-top'
Updates Makefile.ifort to compile top.f90 and oneTwoDecompose.f90
