+This routine can be customized to push grade information to some other gradebook,
+LCMS, or administrative system external to LON-CAPA.
+
+export_grades() takes five arguments -
+(a) the LON-CAPA course ID
+(b) the LON-CAPA course domain
+(c) a hash reference containing the following: 
+    scope    => scope of the grades (e.g., course, map or resource).
+    instcode => institutional course code (if an official course)
+    crstype  => course type -- Course, Community or Placement
+    context  => calling context, e.g., "completion" when a student completes a placement test.
+(d) a perl data structure (hash of a hash) containing the grade data.
+    in the outer hash, the keys are student's username:domain
+    in the inner hash, keys are:  
+    id        => student/employee ID
+    lastname  => student's last name
+    firstname => student's first name
+    email     => student's "permannent" e-mail address
+    section   => student's LON-CAPA course section
+    total     => total points earned
+    bytitle   => reference to a hash (keys are question titles, values are points
+    bysymb    => reference to a hash (keys are symbs, i.e., unique resource identifiers).
+(e) reference to a hash which will contain information to return.
+    keys will be the student's username:domain. Value of 1 to show grades pushed 
+    successfully.
