Better Logging Support

[ialok]

Background

Strabo is exceedingly hard to debug. This is due to lack of a better error notification mechanism. Our Logging is primitive and has tremendous scope of improvement.

Issue

• Lack of log lines
• Custom log class used to save images deviates from the well defined role of Logging
• Lack of logging levels and the logging config fails to provide sufficient details about the program flow

Fix

• Remove the Custom logging class
• Use any c# logging framework. This is gives us better logging mechanism
• Separation of Image I/O from log class
