reasonable program to generate macaulay matrices

should remove empty columns though...

## Macaulay Matrix Generation
`macaulay_gen.c` reads quadratic polynomials and generates a (sparse) macaulay
matrix in which some columns are removed. The sparse matrix format is as
A file `FILE.bin` is expected to contain nrows rows, each coded as the
row length `<nentries>` written as a 32-bit little-endian integer, followed
by the `<nentries>` indices of non-zero columns, all as 32-bit little-endian
The most important parameter (and required) are `--degree` and
`--inner-hybridation`, which specifies the degree of the macaulay matrix and
how many variables are not guessed, respectively.
./macaulay_gen --degree 4 --inner-hybridation 12 --in examples/ --out test.bin
# Polynomials Input format
This code parses polynomial systems modulo 2 in the following format:
