Sherpa Prototype

addNewTest in sherpa.js is now adding either a dup of the last test, if any, or a new test with zeroes everywhere

Both divs used to display results of running program are now in the "Run Tests" tab. A button allows to start the execution / refresh the data presented there. The program is no longer ran every time page_reloaded is executed. This allows for entering stupid values, e.g. variable initializations, without freezing the browser due to an infinite loop.

Adding a dummy test from the view is now possible

Able to remove tests from tests' view

output & tmp variables have now their init values from the header model used for evaluation in evalProgram, more specifically varsExtract. The header's view makes these editable. Presentation of the header's view has been modified a bit.

oops forgot to make the tests descriptions editable too

Tests are editable now. Bit or refactoring in prepareEditables, still much work needed there. In addition prepareEditables & genSimpleHandler need to be factored since they are being used in both TestsView.js & HeaderView.js

programs headers now have a doc property for the author to explain what the program is about. it's editable which led to some refactoring of prepareEditables. Still some improvements needed there but for now it's working
new logError function in org.sherpa to make sure the errors we want to deliverto the programmer will be redirected later to a specific div

Improving JS quality; removing the indexEA index in renderHeader & renderVarList by using editableArray[editableArray.length] to keep adding new elements to the end of this array

fixed missing of 2nd parameter to editable in prepareEditables from HeaderView.js which led to some layout issues when editing
