better debug messages to the math-parser print

[evykassirer]

when the node isn't recognized, it'd be nice to print some tip to what the node looks like

[ericluap]

Do you mean when it just prints out 'extra input not recognized'?

[evykassirer]

I think I saw "node not recognized" but that place seems good to add detail to as well! :)

[ericluap]

With those, the node that wasn't recognized is also printed. I think the only place it isn't printed out is with the extra input error.

[evykassirer]

I believe it was this line

math-parser/lib/print.js

Line 144 in 65fef14

throw new Error('unrecognized node')

[evykassirer]

the node is logged but not part of the error, so I couldn't see it

[ericluap]

Ah ok, missed that one entirely.
