Remarks
This class takes all protocol frame parsing implementations and reduces them to a single simple-to-use class exposing all
data through abstract interfaces (e.g., IConfigurationFrame, IDataFrame, etc.) - this way new protocol implementations can
be added without adversely affecting consuming code. Additionally, this class implements a variety of transport options
(e.g., TCP, UDP, Serial, etc.) and hides the complexities of this connectivity and internally pushes all data received from
the selected transport protocol to the selected phasor parsing protocol.
