issues of multigrading.lib

[hannes]

(NOTE: we are prepearing for a minor Singular release at the end of March...)

Here are some issues of multigrading.lib:

fixed:

1. is missing intDet (in example intInverse, primitiveSpan,...)
2. + some other bugs
3. comment out 'mDegTruncate' (too experimentall)
4. fix: projectLattices -> projectLattice

open: . missing documentation: 'mDegTensor', 'mDegTor', 'gradiator'

. missing examples: 'createQuotientGroup', 'createTorsionFreeGroup', 'isGroup', 'getGradedGenerator'

. some examples are still "TODO"

. global procs projectLattice/mDegTruncate are not found in header

. fix: projectLattice

./examples/projectLattice.sing   1> LIB "multigrading.lib";
./examples/projectLattice.sing   2> intmat B[4][2] =
./examples/projectLattice.sing   3. 1,5,
./examples/projectLattice.sing   4. 2,6,
./examples/projectLattice.sing   5. 3,7,
./examples/projectLattice.sing   6. 4,8;
./examples/projectLattice.sing   7> // should result in a (2x4)-matrix with columns
./examples/projectLattice.sing   8. // [-1, 2], [2, -3], [-1, 0] and [0, 1]
./examples/projectLattice.sing   9. intmat U = projectLattice(B);
   ? rows must be greater than 0
   ? error occurred in or before multigrading.lib::projectLattice line 4795: `      intmat Udel[nrows(U) - r][ncols(U)];`
   ? leaving multigrading.lib::projectLattice
   skipping text from `;` error at token `)`
STDIN   1> $

. implement areIsomorphicGroups and use it somewhere...

TODO for later (after the Release): . groups should be in a separate library (name: ?)

the latest version (from Google Code) seems to be fine!
