def mapify(string):

def DybPython::Tools::mapify

(

string

)

Parse string, return dictionary.  The string can be either in
the form of a Python dictionary, in which case it is simply
eval'ed or it can be of the simpler form of key/value pairs
separated by a colon (":") and with pairs separated with spaces.
This simpler form assumes all keys and values are themselves to be
interpreted as strings unless they begin with an "[" in which case
they will be eval'ed.

def unitify(string, default_unit=None):

def DybPython::Tools::unitify	(		string,
			default_unit = None
	)

Evaluate the given string in a context with units defined.  If
default_unit is given it will be implicitly multiplied 

Examples:

1 == unitify("1")
1.1 == unitify("1.1")
1000000000.0 == unitify("second")
1000000000.0 == unitify("1*second")
1000000000.0 == unitify("1","second")
1000000000.0 == unitify("1",units.second)
