+Before predictive text entry systems like T9, you had to press a button
+repeatedly to cycle through the possible values until you reached
+the one you wanted.
+
+For example, to type "V8" you would press the 8 key three times and then
+again four times (pressing the 8 key cycles through T->U->V->8),
+giving us a total of seven key presses.
+
+Note: the 0 key handles spaces and outputs 0 when tapped twice.
+
+Write a function that can calculate the amount of button presses required for any phrase.
+Except for spaces, punctuation can be ignored.
+Your function should accept both uppercase and lowercase letters and treat them the same.
+
+Examples:
+presses('V8') # 7
+presses('LOL') # 9
+presses('How R u 2day') # 23
+
+Bonus:  Try to avoid hard-coding the number of button presses for each letter!
