las2txt -parse option

[mpg]

Adding a new option to "-parse" that writes out the index number of the vertex would be good, as this would add compatibility with the ".node" file format that Shewchuk's triangle tool uses.

Example (calling the new option 'M'):

-parse Mxyz

would produce an output like

0 289814.15 4320978.61 170.76
1 289814.64 4320978.84 170.76
2 289815.12 4320979.06 170.75
3 289815.6 4320979.28 170.74
4 289816.08 4320979.5 170.68
5 289816.56 4320979.72 170.66

(reproducing the example output, with proper linefeeding)
