Added qrings feature for constant in ideal
Added tests Tst/New/qring_with_constant
Forgot to rewrite the test New/qring_with_constant
Updated Short/ringmaps.tst since it has been added a nrnMapProjective from Z/p^s to Z/p^t with s > t
mv: moved the qring constant build into a function
add: cfQuot1
del: deleted not needed functions and chg names of functions

Qrings
towards a uniq n_Div: removing some of n_IntDiv
fix: ksCheckCoeff: may be used with coeffs in Q
Added DebugPrinting for numbers

Note/Update: StringUpdate => StringEnd
Defined libkernelCommon.la to be the actual shared part of libkernel.la
The header kernel/combinatorics/hutil.h should not depend on currRing
Templates for unit testing kernel subparts (like kernel/GBEngine, kernel/combinatorics, kernel/fglm etc...)
further Syz/Resolutions:

chg: sorting: "ds" ->> "c,ds" (since reversed order!)
chg: SSComputeLeadingSyzygyTerms moved into the dynamic module (ComputeLeadingSyzygyTerms)!

TODO: add id_Sort wrt "c,ds" to ComputeLeadingSyzygyTerms???
sorting for Syz/Res project:

add: inplace sorting 'Sort_c_ds'
add: MySort to schreyer.lib for testing 'Sort_c_ds'
chg: ComputeLeadingSyzygyTerms now sorts the output
fix: MySort for non-monomial modules
Added unused GetAMPos/GetAMData helper functions to syzextra
