LineGetPriceOnLogScaleLibrary   "LineGetPriceOnLogScale" 
This library provides a way to calculate the y-coordinate of a line on a specified bar when the chart scale is Log.
The built-in `line.get_price()` function only works with linear scale and gives incorrect results when the chart is in Log scale.
The library only works with `bar_index` values and `xloc.bar_index`-based lines, `time`-based lines will cause errors to appear.
 coordGetPriceLog(x1, y1, x2, y2, xi)  Calculates the y-coordinate on the specified bar on the logarithmic scale. 
Only coordinates based on bar index are applicable, bar time will throw an error.
	Parameters:
 	 x1 : First X coordinate of a line, index of the bar where the line starts.
	 y1 : First Y coordinate of a line, price on the price scale.
	 x2 : Second X coordinate of a line, index of the bar where the line ends.
	 y2 : Second Y coordinate of a line, price on the price scale.
	 xi : Index of the bar for which the price should be calculated. 
	Returns: Price of the line on the bar specified in `xi`, on the logarithmic scale.
 lineGetPriceLog(_line, xi)  Calculates the y-coordinate on the specified bar for the logarithmic scale. Takes a line.
Only lines drawn based on `xloc.bar_index` are applicable, `xloc.bar_time` will throw and error.
	Parameters:
 	 _line : The line for which the price is calculated.
	 xi : Index of the bar for which the bar should calculate the price. 
	Returns: Price of the line on the bar specified in `xi`, on the logarithmic scale.
