Detailed Description
This implements a dynamic matrix when we have a limit on the number of "interesting rows".
This version inherits from ClpDynamicMatrix and knows that the real matrix is gub. This acts just like ClpDynamicMatrix but generates columns. This "generates" columns by choosing from stored set. It is maent as a starting point as to how you could use shortest path to generate columns.
So it has its own copy of all data needed. It populates ClpDynamicWatrix with enough to allow for gub keys and active variables. In turn ClpDynamicMatrix populates a CoinPackedMatrix with active columns and rows.
As there is one copy here and one in ClpDynamicmatrix these names end in Gen_
It is obviously more efficient to just use ClpDynamicMatrix but the ideas is to show how much code a user would have to write.
This does not work very well with bounds

This is the real constructor.
It assumes factorization frequency will not be changed. This resizes model !!!! The contents of original matrix in model will be taken over and original matrix will be sanitized so can be deleted (to avoid a very small memory leak)

| double | start, | |||
| double | end, | |||
| int & | bestSequence, | |||
| int & | numberWanted | |||

Partial pricing.
Reimplemented from ClpDynamicMatrix.
| virtual void ClpDynamicExampleMatrix::createVariable | ( | ClpSimplex * | model, | |
| int & | bestSequence | |||

Creates a variable.
This is called after partial pricing and will modify matrix. Will update bestSequence.
Reimplemented from ClpDynamicMatrix.
| virtual void ClpDynamicExampleMatrix::packDown | ( | const int * | in, | |
| int | numberToPack | |||
| ) | [virtual] |
If addColumn forces compression then this allows descendant to know what to do.
If >= then entry stayed in, if -1 then entry went out to lower bound.of zero. Entries at upper bound (really nonzero) never go out (at present).
