Including processes
BI# supports modular software design and reuse. Its most important tool
				is the #include statement. It allows to define a set
				of functions in a single place and use it wherever required. If you have a
				mathematical function stored in a process named math.bs, for example, you can include it into your own process with
				this statement:
 #include "math.bs", "1.0" 
		       The #include statement expects two
				arguments. The first argument is the name of the process to be included. The second
				argument specifies the version of the process to include.
If you always want to include the latest version of a process, set the
		  process version to 
		  "*". For example: 
		
#include "booking", "*" 
		       This statement always includes the latest version of the process named
					"booking".
