Updates from Jowr/librefprop.so to work for maci64

read me and matlab folder updated
Editing for clarity
Changes for Linux 64 bit no root user access

Please note this was specifically drawn up for use on a super computer
where the working directory is typically /scratch/USERNAME
Merge remote-tracking branch 'nkampy/Linux-64-bit-install' into develop for testing and integration
Reset to jowr initial paths
Ignore some more files
Reset to jowr path in the fortran exemple too
Merge pull request #12 from nkampy/master

MACI64 bit method
Merge pull request #11 from nkampy/Linux-64-bit-install

Linux 64 bit install
Merge remote-tracking branch 'jowr/master' into develop to take in account the modifications jowr accepted in the master branch from nkampy
Added a function to test if the file to patch exists in the current folder
Added a case statement to perform the right operations depending on the computer architecture (32 or 64 bits)
Merge pull request #16 from speredenn/develop

new fixfiles.sh + default PATH back before we get the customizable paths in the makefile
Added some commands for non root users, needs testing.
Tested Makefile and restored example paths
Update readme.md

Added a little text on exports
Tried to further integrate the matlab scripts. Testing is needed! Things might work on 64bit Linux, but MacOS still remains untested...
Fixed a typo... Works on 32bit Linux now.
Merge remote-tracking branch 'jowr/master' into develop
New makefile :-)
Better rm -f **.o **.so **.a **.dylib **.mod ./bin/* ./src/*.o ./fortran/*.f ./fortran/*.f.du ./fortran/*.o ./src/PASS_FTN_ALT.f ./src/PASS_FTN_ALT.f.du ./matlab/r*.m.* ./matlab/*.so command
