CurlySMILES class Notation: method numof_components

Method numbof_components belongs to class Notation, the core class for managing a CurlySMILES notation.

Module: csm_notation.py
Method: numbof_components()
Argument: no argument
Return: nComponents, an integer with the number of components (dot-separated parts) in the work notation of a given notation.
Example: For the CurlySMILES notation of cobalt(II) nitrate hexahydrate, Co(NO3)2·6H2O

___ sNotation = '[Co+2].[O-]N(=O)=O{2}.O{6}'

the call

___ nComponents = oNotation.numof_components()

makes the assignment

___ nComponents = 9

since the work notation is

___ sWorkNotation = \
______ '[Co+2].[O-]N(=O)=O.[O-]N(=O)=O.O.O.O.O.O.O'
