+Information for developers
+
+Coding Conventions:
+
+* Classes are Uppercase, methods and functions lowerMixedCase
+* We use a modified K&R Style, with 2-space tabs, inserting spaces for tabs
+* Use meaningful variable names, e.g., measurement not msm
+
+
+Windows:
+
+On Windows it is necessary to explicitly export all functions from the library
+which should be externally accessible. To do this, include the macro 
+GTSAM_EXPORT in your class or function definition.
+
+For example:
+class GTSAM_EXPORT MyClass { ... };
+
+GTSAM_EXPORT myFunction();
