      As identified in MDL-48273, the single view report loads every single user with active enrollment in the memory. This leads to two main problems:-

      1. High memory usage.
      2. The ui to select user becomes an extremely long drop down for large courses.
        (Note:  This is no longer relevant after 4.2 - the old user select has been replaced with a new component that addresses this problem)

      Suggested changes:-

      1. Show a search user interface instead of drop down when Number of users exceed a certain value say X.
      2. Load only the required users in memory at best this should never exceed X
