Read me clarification required

As per blog post comment...

"Andrew – I wanted to provide you some feedback for the short few days I’ve been using this tool. I haven’t been able to fully test it since the calculations I have are on existing records. But I did want to let you know about one small glitch I ran into in installing/setting up the tool. Part of this is my lack of knowledge on installing APEX tools. It works great for the System Administrator, but when another user in another Profile tried to enter a new record that was being affected by the tool, it gave an error message and would not save the record. It took me a little while to figure out where in the Profile to fix this but I managed to figure it out.
It would be great if during the setup/install of the tool, there was a prompt to ask which Profiles you want to enable the tool on, to save the Admin the time to do that separately. And if this can’t be done, then to provide simple instructions on where to go to activate it for each set of users beyond the system admin."

"Thanks for this great feedback! I will add a section to the readme file describing which operations need what profile settings to clarify this better. Thanks again!"
