Akari Masyu

Description
Akari Masyu is a hybrid of Akari and Masyu, in which the cells in a grid are lit-up by placing lightbulbs and no lightbulbs shine on each other and a single, non-intersecting loop that passes through all empty cells is drawn.

Rules
The objective is to light up all white cells, and draw a single, non-intersecting loop, subject to the following rules:
 * 1) Lightbulbs shine every cell vertically and horizontally until they reach a black cell or the boundary.
 * 2) Numbers in some black cells denote the number of lightbulbs in adjacent cells.
 * 3) Lightbulbs themselves are not lit by other lightbulbs.
 * 4) All cells not occupied by lightbulbs must contain a single, non-intersecting loop.
 * 5) At black cells the loop has a turn of 90°. The loop must also go straight through the cells immediately before and after on the path.
 * 6) At white cells the line travels straight through. The must turn in the cells immediately before and/or after on the path.
