I have added the initial implementation of the MAD-X parser.

As it MADX is a complete scripting language, this parser only implements a subset of the MAD-X statements. But it should be sufficient for most lattice files:

it can evaluate arithmetic expression
one can use variables
it understands inversed/multiplied sequences

One outstanding issue is, that LatticeJSON has currently no DipoleEdge element, because the entrance and exit angles can also be set in the Dipole definition.

This leads to the Problem that Dipedge elements of MADX are replaced by Drift spaces. This is indicated by a warning.
