Interface FunctionExtension

public interface FunctionExtension
FunctionExtension provides interface for function algorithm definition. In this case algorithm definition is based on source code using JAVA (for JAVA / Android) or .NET. If implemented Function Extension object can be further used while Function object construction, which means it can extend mXparser math collection. mXparser extension with your own implementation can be achieved by implementing FunctionExtension interface, creating an FunctionExtension object, creating Function object based on FunctionExtension, adding Function object to Expression / mXparser definition.
