Build a pool of training observations for a grade level

1	buildTrainingPool(grade, conn)

`grade`	a numeric representing the grade level we are interested in finding training cohorts for
`conn`	a connection string which contains links to databases necessary to extract the data

This function identifies the number of grade N cohorts which have valid graduation outcomes and then pulls all complete observations from those cohorts using the assembleCohort function. It then stacks all of these cohorts into a single data.frame suitable for transformation and analysis later. At the end it calls cleanTrainingPool to clean up the data and enforce business rules about variable encoding.

a data.frame with all colums generated by assembleCohort and the number of rows equal to the number of students per cohort X the number of cohorts available for a given grade
